No, that's not what I meant at all.

Dean asked me: "Did you mean to reply to list?" (or something like)

So I replied: "Yes, Dean I meant to reply to list, but I had a problem
with Gmail" Then I went on to explain the bug of why reply to list
failed. The problem I had was trying to reply to the list and GMail
had a bug in my particular use-case. Nothing to do with Generics.

My original message had to do with cases of dealing with handling a
case of Array generics with a non-Array-like argument.
